The DBFS Content API aggregates the path namespace of one or more stores into a single unified namespace.
The first component of the path name is used to disambiguate the namespace and then present it to client applications. This allows clients to access the underlying documents using either a full absolute path name represented by a single string, as shown in the following code snippet:
The DBFS Content API then takes care of correctly dispatching various operations on path names to the appropriate store provider .
Store providers must conform to the store provider interface (SPI) as declared by the package
